Tuen Mun–Chek Lap Kok TBM
The Tuen Mun - Chek Lap Kok TBM otherwise known as Qin Liangyu or more formally, the Mixshield S-880 was the world's largest tunnel boring machine launched in June 2015 by Herrenknecht in Germany. The TBM was used to drill a 5 km tunnel connecting Tuen Mun to the Hong Kong International Airport, part of the Tuen Mun–Chek Lap Kok Link project. The contract for the project was around HK$ 18.2 billion (US$ 2.3 billion) Specifications The machine had a diameter of , more than Bertha, the previous largest tunnel boring machine A tunnel boring machine (TBM), also known as a "mole" or a "worm", is a machine used to excavate tunnels. TBMs are an alternative to drilling and blasting methods and "hand mining", allowing more rapid excavation through hard rock, wet or dry so .... Outside of its cutting diameter, it had an overall length of 120 metres (393 ft 8 in) and weighed 4,850 tonnes (5,346 US-tons).

Tunnel Boring Machine
A tunnel boring machine (TBM), also known as a "mole" or a "worm", is a machine used to excavate tunnels. TBMs are an alternative to drilling and blasting methods and "hand mining", allowing more rapid excavation through hard rock, wet or dry soil, or sand (although each requires specialized TBM technologies). TBM-bored tunnel cross-sections extend up to (through June 2023). TBM tunnels are typically circular in cross-section, but may also be square or rectangular, or U- or horseshoe-shaped. Much narrower tunnels are typically bored using trenchless construction methods or horizontal directional drilling rather than by TBMs. TBMs limit disturbance to the surrounding ground and produce a smooth tunnel wall, which reduces the cost of lining the tunnel; it also allows for tunneling in urban areas. Large TBMs are expensive and challenging to construct and transport, fixed costs which become less significant for longer tunnels. Tunneling speeds generally decline as tunnel size in ...

Tuen Mun–Chek Lap Kok Link
The Tuen Mun–Chek Lap Kok Link (, abbreviated as TM–CLKL) is a road project in the New Territories, Hong Kong. It comprises two elements: the "Northern Connection" and the "Southern Connection". The Northern Connection comprises an undersea tunnel crossing the Urmston Road, linking Tuen Mun to the "Boundary Crossing Facilities" (BCF), an artificial peninsula connected to Hong Kong International Airport. The Southern Connection, officially named Shun Long Road (), comprises viaducts linking the BCF to North Lantau Highway on Lantau Island. The construction of the link has helped facilitate travel between the Northwest New Territories (Tuen Mun and Yuen Long Districts) and the Hong Kong International Airport and the Hong Kong–Zhuhai–Macau Bridge (Hong Kong Port). Though the project lies entirely within Hong Kong territory, its construction is associated with the new Hong Kong–Zhuhai–Macau Bridge The Hong Kong–Zhuhai–Macau Bridge (HZMB) is a bridge–tunnel ...

Hong Kong Dollar
The Hong Kong dollar (, sign: HK$; code: HKD) is the official currency of Hong Kong. It is divided into 100 cents. Historically, it was also divided into 1000 mils. The Hong Kong Monetary Authority is the monetary authority of Hong Kong and the Hong Kong dollar. Three commercial banks are licensed by the Hong Kong Monetary Authority to issue their own banknotes for general circulation in Hong Kong. These banks, HSBC, Bank of China, and Standard Chartered, issue their own designs of banknotes in denominations of HK$20, HK$50, HK$100, HK$150, HK$500, and HK$1000, with all designs being similar to one another in the same denomination of banknote. However, the HK$10 banknote and all coins are issued by the Government of Hong Kong. the Hong Kong dollar was the ninth- most traded currency in the world. Hong Kong uses a linked exchange rate system, trading since May 2005 in the range US$1:HK$7.75–7.85. Apart from its use in Hong Kong, the Hong Kong dollar is also used in ...

Herrenknecht AG
Herrenknecht AG is a German company that manufactures tunnel boring machines (TBMs). Headquartered in Allmannsweier, Schwanau, Baden-Württemberg, it is the worldwide market leader for heavy TBMs. Established by Martin Herrenknecht in 1975, the company soon grew. Its first overseas subsidiary, ''Herrenknecht International Ltd'', was created in 1984; a further 79 subsidiaries would be set up or purchased over the next 30 years to provide global coverage. Its products have often pushed technological boundaries; a Herrenknecht-built TBM in the late 1990s was the largest in the world at that time, while the world's longest and deepest railway tunnel (the Gotthard Base Tunnel) was bored using the company's apparatus. By 2015, the company had around 5,000 employees. History Martin Herrenknecht established the Martin Herrenknecht engineering company in 1975; it initially had six employees. Two years later, it became Herrenknecht GmbH, at which point it had a capital of 20 million eu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tuen Mun
Tuen Mun () or Castle Peak is an area near the mouth of Tuen Mun River and Castle Peak Bay in the New Territories, Hong Kong. It was one of the earliest settlements in what is now Hong Kong and can be dated to the Neolithic period. In the more recent past, it was home to many Tanka fishermen who gathered at Castle Peak Bay. Tuen Mun is now a modern, mainly residential area in the north-west New Territories. As of 2025, around 540,000 residents live in Tuen Mun. History During the Tang dynasty (618907), a navy town, Tuen Mun Tsan () was established in Nantou, which lies across Deep Bay. Tuen Mun and the rest of Hong Kong were under its protection. A major clan, To (), brought the name Tuen Mun to the area. They migrated from Jiangxi on the Chinese mainland and established a village, Tuen Mun Tsuen (),Antiquities and Monuments OfficeTuen Tsz Wai - History/ref> late in the Yuan dynasty (1272–1368).

Bertha (tunnel Boring Machine)
Bertha was a tunnel boring machine built specifically for the Washington State Department of Transportation's (WSDOT) Alaskan Way Viaduct replacement tunnel project in Seattle, Washington (state), Washington, United States. It was made by Hitachi Zosen Corporation, Hitachi Zosen Sakai Works in Osaka, Japan, and the machine's assembly was completed in Seattle in June 2013. Tunnel boring began on July 30, 2013, with the machine originally scheduled to complete the tunnel in December 2015. On December 6, 2013, work was halted approximately into the planned route because of an unexpected impediment. It was thought that several cutting blades were damaged by striking a steel pipe that had been used to measure groundwater in 2002 around the Alaskan Way Viaduct. However, subsequent investigation revealed that portions of the main bearing seal system were damaged, causing the bearing to overheat during operation. Over the next two years, a recovery pit was dug from the surface in ord ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
